The life of the HES began in , ended . The first hydroelectric unit was put into operation at the HPP on the 17th of March. HES was inspired by the rowing-derivation type. Spore warehouse HES:
- bulky rowing of the windrower 700 m-code and the highest height of 19.5 m-code;
- concrete water skid at the tіlі bulk rowing;
- derivation subway canal with a length of 500 m;
- pressure vuzol from metal pipelines;
- budіvlya GES zavdovka 49 m;
- canal, which leads to the valley of 1310 m.
The intensity of the HPP is 80 MW, the average vibration is 346 million kWh per year. Two rotary-blade hydraulic units with a capacity of 40 MW each were installed near the hydroelectric power station, which work with a 32-meter surge pressure. Napіrnі spores of hydropower station (dovzhina of the pressure front 0.76 km) establish the Kumsk reservoir, which included Kundozero, Pyaozero and Topozero. The area of the reservoir is 1910 km², the total capacity is 9.83 and 8.63 km³. At the hour of the watershed's creation, 760 hectares of agricultural land were flooded, 200 days were moved.
The HPP was designed by the Lengiroproekt Institute.

Geographically, the Kumska HPP is located in Karelia, but there is only one line that goes to the station, along with the energy system of the Murmansk region.
Design-vishukuvalnі roboti was rozpochato in 1951 roci. With this, the basis for the life of the hydroelectric station became geological guards, built up a quarter of a century earlier.
On the back of the heads of fakhіvtsy looked underground roztashuvannya engine room. But the introduction of the underground HPS took two more years to complete, due to the complete lack of preparation for the underground work. The possibility of the Swedish introduction of the station, not respecting the zbіlshennya obyagu of land and cellar robots, was virishal.
The operation of the HPP began in 1961, and after 20 months the hydroelectric station was brought to full of tightness 80 MW.
Another unique feature of the Kumskaya HPP is those that the station was planned to be serviced without operational staff, on TV. However, through the introduction of system solutions in the automation of control systems in the 1960s, the years before the implementation of the idea turned significantly later. Telecontrol and telecontrol were introduced in 2009.
- Inserted electrical pressure- 569.5 MW
- Electricity generation - 2,957.4 million kW/year.
One of the main sources of electricity in the Kola Pivostrovo. Stations of the Cascade vibrate over a third of all electric power, which is victorious in the Murmansk region.
Warehouse cascade
- Niva GES-1 (launched on December 25, 1952)
- Niva GES-2 (launched on the 30th of March 1934)
- Niva GES-3 (launched on December 20, 1949)
- Kumska HPP (commissioned on December 30, 1962)
- Iovska HPP (commissioned on December 28, 1960)
- Knyazhegubskaya HPP (commissioned on 21 July 1955)
Niva GES-1
The first black Niva GES-1 bula was put into operation in 1952, the rest of the life ended in 1954. The development of the pіvnіchnyh shores went by force, a lot of engineers and budіvelniki were directed here from the forward station - the underground Niva GES-3.
This station is the first on the cascade, a telemechanics was installed, which allowed the work to be carried out without the presence of a permanent operational staff. In Denmark, it will be more automated. Zdijsnyuє rіchne that bagatorіchne regulation of the flow of bunks. Nivi by the reservoirs of lakes Imandra and Pirenga.
The intensity of the Niva GES-1 is 26 MW, the average production of electricity is 131.641 million kWh.
Niva GES-2
The first HES Cascade, Niva HES-2, is not enough to become the energy center of the region, even rich in deposits of apatite-nepheline ores, found in Khibiny, their kind of mining from apatite concentrate was a significant source of energy base.
In 1930 in line with the GOELRO plan near the river valley. The life of the hydroelectric power station Niva GES-2 has changed in the Niva.
The station was designed and built overnight. With all the engineers, and the alarm workers, there was no shortage of work for the folded minds of the Krainyo Pivnoch. IN style terms He was able to block the old river bed, lay a canal, which was to be led in, at a distance of 4.5 km and encourage the head of the station. The launch of the first hydroelectric unit took place on 30 March 1934.
In 1936 REU “Kolenergo” was created on the Kola Pivostroy, to the warehouse of which Niva HPS-2 was taken from Murmansk TPP and Nizhnyo-Tulomsk HPP at once.
Spring 1946 after the invigorating robots Niva GES-2 was able to reach its design tightness again.
The Niva GES-2 pressure was installed - 60 MW. Average generation of electricity - 365.26 million kWh.
Niva GES-3
For example, the 1930s. the work of the life of the first underground station near the Radyansk Union was roared. For the hour of the war, everyday life was frozen. Start of the first draft Niva GES-3 in 1949 This station is unique: її the machine room of the milling at the top of the rock, on a depth of 76 meters from the surface.
Niva HES-3, the lower slab of the Nivskiye HES cascade, was laid out 5 km away from the Kandalaksha Guba of the White Sea.
The Niva GES-3 pressure was installed - 155.5 MW. Average generation of electricity - 877.02 million kWh.
Kumska GES
In the 1950s, after the completion of work on the Nivsky Cascade, hydrobuds began before the development of the Kovda river.
The life of the HES began in 1961 and ended in 1963. They called Kumsk HPP at the same time from Iovskaya HPP. The first hydroelectric unit was put into operation on December 30, 1962, and for example, in 1963, the Kumska hydroelectric station was taken over by industrial operation.
The main hydroelectric station of the “Kolska” branch was laid out outside the borders of the Kola Pivostrov - on the territory of the Republic of Karelia.
Napіrnі spores of HPPs make up the Kumsk reservoir, which included Pyaozero and Topozero. Reservoir area 1970 sq. km. Under the hour of the creation of the reservoir, 200 days were moved. The HPPs are equipped with rowing rowing with a maximum height of 721 m and a maximum height of 19.6 m, a diversion canal, which can be brought in, with a maximum height of 500 m and an external canal with a maximum height of 1306 m
The power plant has been installed - 80 MW, the average power generation - 355.56 million kWh.
Iovska HPP
The life of the Iovskaya HPP began in 1958 and ended in 1963. The first unit was put into operation on December 28, 1960 - after placing the robot under a wooden tent, the hydroelectric power station was called after the launch. On February 17, 1965, the Iovska HPP was taken into commercial operation.
The cascade of the Kovdinsky HPPs was created at once from the Kumska hydroelectric power station.
The river Kovda before the life of the HES was a lazy lake, crossed by short rapids channels. At least the rest of the channel, which gives water to the sea the Kovdozero, the rest of the lakes lansyzhka, small im'ya in the Kovdi river. Other ducts, though and vvazhayutsya warehouse lanes of Kovdi, with special names: lake. Topozero, nar. Sof'yanga, oz. Pyaozero, nar. Kundozerka, oz. Kundozero, people Kuma, oz. Sokolozero, nar. Rugozerka, oz. Rugozero, nar. Kovdochka, oz. Sushozero, nar. Iova (abo Upper Kovda), lake. Kovdozero, nar. Kovda.
To increase the efficiency of the station, an original engineering solution was adopted: a stack of Tavand and Tolvand lakes was thrown over at the watershed of the HPP. Napirnі spores of HPS include 3 rowing rows with a length of 350, 500 and 1180 m. m, which includes sprats of lakes.
The power density was installed - 96 MW, the average volume of electricity generation - 508.39 million kW / year.
Knyazhegubska GES
Knyazhegubska HPP is the first of the 3 stations, located near the lower water system of Kovdi, on a new man-made river branch. The piece canal drains the water of the Kovdozero (Knyazhegubsky reservoir) near the Beale Sea in the shortest way. For the sky of which I “break through” to the sea at a short distance, a great elevation difference is reached, which is necessary for efficient work GES.
The terms for the launch of the ownership of the Knyazhegubskaya HPP were unique. The first unit was built on July 21, 1955. Another - 23 leaf fall, the third - 29 breasts of the same fate. With the launch of the fourth unit, which happened on February 28, 1956, the station entered design pressure. Todi won 128 MW, but in the next hour of modernization it went up to 152 MW.
At once, with the life of the Knyazhegubskaya station, the settlement of Zelenoborsk vanished, for which HES the dosі is filled with mysto-creating hospitality.
The Knyazhegubsk power plant is built up from a small number of hydroelectric hubs. At sporudi HPP incoming nasipna rowing Tup'єgubskogo gіdrovuzla zavdovzhki 962 m, nasipna rowing Lyahkomіnskogo gіdrovuzla (952 m), nasipna rowing Knyazhegubskogo gіdrovuzla (628 m) of naybіlshoyu visota 20.8 m, concrete vodoskidna rowing Lyakhi nasipnih Hrebel Lyahkomіnskogo gіdrovuzla zagalnoyu dovzhinoyu 1465 m.
The installed pressure is 152 MW, the average volume of electricity generation is 751.711 million kWh.
